Breath on a cold day

Your breath is warmer than the air outside on a cold day. When you breathe in, your lungs warm up the air because your body has a constant temperature of 37 Degrees Celsius. If the temperature of your breath suddenly decreases (like when you breathe out), condensation can occur, which is a bit like steam. This makes your breath turn to fog and dust in the air also helps you see it.

This is why you see your breath on a cold day.
